Hi,
I am trying to enable the app_python module in Kamailio to run a simple python script
externally parallel with Kamailio proxy,
While I try to load the module "app_python.so" in configuration file, the
Kamailio server fails to start.. I can't see what is the problem ..
The steps, I am following are that:
- Script written in python saved in home directory.
- Loadmodule "app_python.so" statement in configuration file.
- Modparam("app_python", "script_name", "location of
script")
- Python_exec("function", "parameters list") ..
I have also tried to check the Kamailio configuration option, It gives following
warning,
0(2942) WARNING: <core> [sr_module.c:584]:
/usr/local/lib64/kamailio/modules/app_python.so: exports dlflags interface is deprecated
and it will not be supported in newer versions; consider using mod_register() instead
I am wandering if any one can please help in this matter, I shall be very thankful ..
With many thanks ..
Kind Regards,
Nasir

Is there no other error message? What you provided is just a WARNING

Hi Timo,
Yes, I have investigated it a bit more. The problem is not that warning it is an error
which stops the Kamailio to start..
The error is
"0(25062) DEBUG: <core> [sr_module.c:885]: DEBUG: init_mod: app_python
0(25062) ERROR: app_python [python_mod.c:158]: cannot import handler
0(25062) ERROR: <core> [sr_module.c:889]: init_mod(): Error while initializing
module app_python (/usr/local/lib64/kamailio/modules/app_python.so)
ERROR: error while initializing modules"
I have tried to investigate a bit more, and the problem is that it is not able to find the
handler.py file..
The error is occurring in init_mod() function which is trying to call a function called
"PyImport_ImportModule(bname)" function.. The file tries to set the absolute
path in the start .. The absolute path was setup with reference to "sip-router"
folder which is old.. So, I changed the path to Kamailio folder.. But, the module
can't be loaded...
To investigate this loading problem, I have seen the functions being called.
PyImport_ImportModule takes the name of module to load.. if "." is used that
specifies the sub modules..so, this function is being passed just the word
"handler".. The absolute path in the start is setup for a file called
"handler.py".. This file is trying to push the directory path in the path as
well, but I think maybe there is some problem lying.. I tried to load by passing full path
name to PyImport_ImportModule() as well but, in vain..
Hope this clarifies things more..
Regards,
Nasir
